What are the problems with air leg rock drills

The current air leg rock drills are still used more frequently, so do you know any other problems with it? It is a fast and efficient rock drilling machine. It is widely used in rock tunnel excavation and various rock drilling operations to drill blast holes. It is an important machine in stone works such as mines, railways, transportation, and water conservancy construction.

Problems with air leg rock drills 

1. The key non-hazardous performance of the product has not been highly valued

The air leg rock drill is a hand-held tool machine used for coal mine rock drilling and blasting and bolt support projects. Personal accidents are often caused in applications. however. The critical non-hazardous issue has not yet attracted the attention of manufacturers and users.

The high noise and high vibration of air leg rock drills have serious harm to the physical and mental health of workers. Has been listed as a monitoring target worldwide. Our country has begun to pay attention. But to this day. The manufacturer’s product performance has not yet given specific noise and vibration values, only vague noise indicators are listed, and there is no difference between different manufacturers and different products: and in the use unit, almost no coal mine regards noise and vibration indicators as the indicators. For key performance. The "experience" of "multi-rock drill operation" for decades is still continuing, and some underground operations have a noise as high as 130dB(A). As a result, tens of thousands of coal miners suffer from deafness and palpitation caused by high noise. As for the vibration index, my country's product standards have not yet specified it.

2. Improper competition at low prices seriously affects product reliability 

There are many manufacturers of air leg rock drills. The level is uneven, and products often compete at low prices; users often disregard technical performance, drive down product prices, and affect the sound development of products.

3. The performance of the rock drill is uneven The performance of the air leg rock drill should be reflected in: within the limits of noise, vibration, and machine weight, it has a high drilling speed and low air consumption. The factors that affect the drilling speed are mainly impact power (impact energy and impact frequency), rotation torque and speed, and propulsion performance (propulsion force and propulsion status). The performance of different manufacturers is quite different.
